Miley Cyrus admits she used to bully Hailey Baldwin as a childReuters

Miley Cyrus used to bully Hailey Baldwin when she was a child. During an episode of Carpool Karaoke, the former Disney star admitted she was not good to Justin Bieber's wife during the old days.

During the session, Cyrus was joined by Hailey and Kendall Jenner for a ride, and the trio talked how they knew each other during childhood.

'The Party in the USA' singer was friends with Hailey's older sister Alaia Baldwin, and the 22-year-old model did not have a good time when they got together.

"I would be evil to her," Cyrus admitted. "She would try to play with us, like me and Alaia...we would lock her out of the room...and be evil."

Hailey added: "My older sister and her used to gang up on me."

The Wrecking Ball hitmaker justified her action saying, "I had to. It made you who you are. It made you stronger. Now you can always take the trolls and s**t because I was such a troll."

Hailey seemed to agree with her and stated, "Miley was the biggest troll to me...she prepared me for this industry."
